FUJI FTU 120C FTU120C PLC Module

This compact PLC module provides integrated control for small automation applications. The FUJI FTU 120C FTU120C combines CPU, I/O, and power supply in one unit. Twelve digital inputs and eight digital outputs handle basic discrete control tasks. Consequently, machine builders can automate simple machines without multiple components.

Technical Specifications of the PLC Module

The FUJI FTU 120C FTU120C measures 140 mm in width and 90 mm in height. Its depth reaches 75 mm for DIN rail or panel mounting. The module weighs approximately 0.65 kg including all processing and I/O circuitry. A front panel LED array shows input status, output status, and power condition. The top side features a built-in programming port and removable terminal blocks. This design stores minimal energy in small filtering capacitors only. Therefore, the PLC contains no batteries for program retention.

Functional Features and Integrated Design

The FUJI FTU 120C FTU120C executes ladder logic programs with 1.0 µs per instruction. You can store up to 4,000 steps of user code in onboard Flash memory. The relay outputs switch 2A at 24V DC or 250V AC loads directly. A built-in RS-232 port allows programming without extra adapters. Consequently, this compact PLC eliminates the need for separate racks and power supplies.

Installation and System Integration

You must mount this PLC module on standard 35mm DIN rail or a flat panel. The FUJI FTU 120C FTU120C requires a 24V DC power supply for operation. Removable terminal blocks accept field wiring from 14 to 22 AWG. The module also supports simple networking with other FTU units. Always verify sensor wiring before applying power to the system.

Maintenance and Operational Benefits

Because the FUJI FTU 120C FTU120C stores user programs in Flash memory, it needs no battery backup. Technicians can remove power without losing any ladder logic or configuration data. The PLC retains all program and register values indefinitely after programming. Consequently, this compact controller offers reliable service for standalone machine control.
